CL5 Thickness Gauge

The CL5 precision thickness gauge offers a full range of functionality in an easy-to-use, compact and rugged package.

The CL5 is used for precise thickness measurements of metal and plastic components whose complex geometry often makes them difficult to inspect with conventional gauges.
The CL5 is able to display the ultrasounic response in real-time by using the optional live A-scan to properly align the transducer and verify the accuracy of the test as components become more complex in shape.
Data management for the CL5 is provided through an optional programmable data recorder, using a standard SD card.
The user-friendly design of the CL5 provides intuitive operation, with easy-to-understand on-screen prompts, without the need for dedicated keys.

  • Optional velocity mode for sound velocity determination

The CL5 is used in various industries, particularly in the automotive and aerospace sectors, as both a quality control and production metrology tool. It can be used to spot check the thickness of incoming material such as steel coil. It can be used to monitor machining operations by carrying out intermediate and final thickness measurements. It can also be used to provide precision thickness measurements of plastic components. The CL5 is compatible with a wide range of contact and delay line probes and its Delay Auto Measurement Mode automatically changes from interface to first backwall to multi-echo measurement when using delay line probes to gauge very thin components.
